[PATCH 06/16] test: add broken roundtrip test

[david at tethera.net]

From: David Bremner <bremner at debian.org>

We demonstrate the current notmuch restore parser being confused by
message-id's and tags containing non alpha numeric characters
(particularly space and parentheses are problematic because they are
not escaped by notmuch dump).

We save the files as hex escaped on disk so that the output from the
failing test will not confuse the terminal emulator of people running
the test.
